Ultrasonic Differential Diagnosis Myometrium Nodes Depending on the Histological Structure of the Tumor

Abstract

Objective: development of ultrasonic criteria simple and proliferating uterine myoma. Materials and Methods. We examined 73 patients with uterine myoma who underwent surgical treatment. Depending on the histological structure of the tumor (a simple myoma or proliferative myoma, including sarcoma) retrospectively compared the ultrasound findings, including data in the В-mode of the uterus and node, high-speed performance, peripheral resistance index, and vascularization index (VI), flow index (FI), vascularization-flow index (VFI) and arterial perfusion index (API). Results. The comparative analysis shows that the majority of sonographic signs and dopplerographic simple and proliferating myomas, including sarcomas of the nature nodule identical. The exception is the character node vascularization (intratumoral or peripheral vascularization), and perfusion of the uterus. Thus, API less than 0.025 s-1 corresponds to a simple myoma, and higher than this value - proliferating myoma and sarcoma, and the threshold value is 7.0% of VI. Simple myoma always had VI less than the uterus, while proliferating myoma and sarcoma - more. Conclusion. To make a decision about the method of treatment of patients with uterine myoma should take into account the data of blood supply to the uterus and node.
